Description

[Detailed Description of the Invention] This invention relates to a frame body that is attached to a local part of a rectangular outer wall panel by adhesive or the like.

As shown in the cross section in Fig. 1, the exterior wall panel is generally made by filling a foamed insulation material 3 such as urethane, expanded polystyrene, or phenolic resin between two hardboards 1 and 2, and adding an outer node board. A structure in which an aluminum plate 4 is attached to the surface of the aluminum plate 10 and a coating 5 is applied to the surface of the aluminum plate is used.

The frame body has a U-shaped cross section with rising pieces 6 and 7 as adhesive surfaces to be bonded to the inner surfaces of the peripheral parts of the hardboards 1 and 2, and in particular, the lengths of the rising pieces 6 and 7 on both sides are Different modified U-shaped frames are used.

This frame body is used when attaching the exterior wall panel to the steel frame (C channel) of a building.

By the way, since such a frame is adhered to the periphery of the outer wall panel as described above, its shape in plan view needs to be the same as the outer periphery of the outer wall panel. As shown in the figure, the vertical frame 8°8 and the horizontal frame 9, 9 cut according to the vertical and horizontal dimensions of the external wall panel are welded end to end to form the outer peripheral shape of the external wall panel. It has the following drawbacks.

In addition, the vertical frames 8, 8 and the horizontal frames 9, 9 are designated as a, b, c,
The reason for joining so that a notch as shown in d is present is that the frame body itself does not require much strength and the material can be saved by the amount of the notch.

First of all, the disadvantages are that it is necessary to cut vertical frames and horizontal frames of various sizes according to external wall panels of different sizes, and when assembling, two vertical frames and two horizontal frames must be cut at the end. Since the soil had to be welded in a total of 4 places, cutting work,
There is a drawback in that the assembly work is extremely time consuming.

Second, since the joints between the vertical and horizontal frames are welded, build-up may occur, which has a structural disadvantage in that when it is glued to the exterior wall panel, the hardboard located at the welded area will float up. be.

Thirdly, each corner of the frame has a notch atbt as described above.
Due to the presence of ctd, the panel corner located in that area, specifically the node board corner, may come into contact with other objects during transportation or transportation, resulting in damage, resulting in a decrease in product value. There are disadvantages such as coming.

Therefore, the present invention is a new invention that can drastically reduce these drawbacks.

The purpose is to provide a useful method.

In order to achieve such a purpose, the frame of the exterior wall panel according to the present invention has two U-shaped frames, which is half the number of conventional U-shaped frames, and each U-shaped frame is bent. As a result, only two joints, such as welding, are required at both ends of the U-shaped frame.

In addition, in order to protect the hardboard corners from damage due to contact with other objects, deliberate cuts are formed in the rising pieces located at the bends.

Next, one embodiment of the present invention will be described based on FIGS. 3 and 4.

As shown in FIG. 3, the frame 10 of the external wall panel consists of two U-shaped frames, particularly modified U-shaped frames 11 and 12, and the longitudinal middles A and B of each frame are arranged at right angles. bend,
Both ends 11a.

1 l b > 12 a t 12 b are joined by welding W or the like.

Before each U-shaped frame 11, 12 is bent,
As shown in the figure, cuts 15 and 16 in the form of inclined doglegs are formed in the rising pieces 13 and 14 on both sides located at the bending points A and B in the middle of the longitudinal direction.

Here, the sloping shape of the dogleg is literally the hiragana "
It refers to the shape of the character <'' rotated by a predetermined angle.

The cut in this shape is formed at the cut-side edge 13a of the rising pieces 13, 14 when the frames 11, 12 are bent with the cut position at the top.

This is to ensure that 14a is present at the bent corner.

In this case, each frame is bent at right angles, so the cut 15
．． It is desirable that the angle θ formed by the upper edges of the rising pieces 13 and 14 is a right angle.

In addition, the reference dimensions for forming the cuts are: 11 = 28 ho, 12 = 19 ho, 13 = 15 ho,
14=10mrn.

However, the height hl of the rising piece 13 is 29 mm, and the height h2 of the rising piece 14 is 20 mm.

Further, the lengths of the frames 11 and 12 are equal and are approximately half of the total length of the outer periphery of the outer wall panel.

The frame of the exterior wall panel having this configuration can be manufactured by the following procedure.

That is. First, a rolled metal strip is unrolled and cut into appropriate lengths.

After forming the above-mentioned cuts in the portions corresponding to the rising pieces on both sides of each cut band-shaped plate body, the rising pieces are made to stand up by pressing or the like.

Next, the band-shaped plate body thus formed as a U-shaped frame body is bent at a right angle with the cut position as the apex, and finally the ends of the two frame bodies are joined by welding or the like.

Since the frame of the exterior wall panel according to this invention is constructed as described above, it has the following effects.

■ Since the proposed frame consists of two U-shaped frames, cutting work and joining work such as welding can be halved compared to conventional frames.

In this case, the proposed frame requires the additional work of bending the U-shaped frame, but this work can be done automatically by the vendor.

Therefore, when looking at the entire manufacturing process, the frame of the present invention has better workability and can be manufactured with higher efficiency than the conventional frame.

■ Also, since there are only two welding points, there is less lifting of the hardboard corners of the external wall panels during build-up compared to conventional frames, and since there are only two welding points, it can be quickly ground by grinding. can be resolved.

■ The cuts formed in the rising pieces on both sides of the U-shaped frame body are in the shape of an inclined dogleg, so if the frame is bent with the cut position at the top, the cut side of the rising pieces will be at the corner of the frame. Edges exist.

Therefore, if the frame according to the present invention is adhered to the periphery of the outer wall panel, one of the rising edges will be located at the hardboard corner of the panel, and the hardboard corner can be protected from damage due to contact.

Therefore, it is possible to improve the product value of exterior wall panels and to significantly reduce the occurrence of defective products.

■ Since conventional frames are joined by welding at all corners, it is necessary to overlap the vertical and horizontal frames to some extent at each corner, but with the newly designed frame, only two corners are welded. It is sufficient to polymerize the glyph frame.

Further material can therefore be saved by not having to polymerize at the other two corners.
